I honestly don't know how there isn't one spec of green in there..not even a little weed of anything, or some new grass tillering after recent rains.
Your soil test doesn't seem that bad, is it perfect soil, no. But you should be able to grow a decent lawn even with how it is. Low pH and Low Organic Matter, but that wouldn't strictly result in what you are seeing. I did a soil test a few weeks ago, and have some major deficiencies, yet grass is thick and green.
If you are going to overseed, do it soon like Gene said. Oct is definitely pretty late for you location for seeding. If your established grass does bounce back, make sure to hit it with few Fall fertilizer apps.
